Since the beginning of this year, according to a small interview, the current power 2835 LED has become the absolute main force of the lighting market. From the perspective of the production of the packaging factory or the application side, it is the king of the light source device.
In fact, this phenomenon has been able to begin to emerge since the second half of 2015. At that time, under the guidance of LED packaging manufacturers, the market demand for 0.5W medium-power LED devices has gradually increased, and more and more manufacturers have entered, resulting in further downward adjustment of costs, prompting the application to come to a larger market.
According to relevant statistics, in April this year, the price of the 5630 LED dropped by 6.5%, and the international brands including Lumileds and LG all had a certain degree of downward adjustment. At the same time, the price of the medium-power 2835 LED was also on the verge of the cost line. %, the further decline of this price will also drive the next rapid increase in this market.
Medium power has become mainstream
At present, there are standard and customized medium power LED series on the market, which has developed into a rich product family, such as the common 5630, 2835, 3030 and other specifications, which has occupied the vast majority of the market share of the lighting market.
“In the past, LED lighting applications were mostly high-power LED packaging products, but with the increasing use of medium-power products, lighting fixtures within 10W have been widely used in medium-power series, including LED bulbs. Most of the application products such as lamps and commercial Par lights," said Wang Gaoyang, deputy general manager of Hongli Optoelectronics.
Indeed, many domestic packaging factories are also attacking the 2835 series products with high current characteristics. Their cost-effective features are also widely favored by lighting manufacturers. In the past two years, they have developed rapidly and have an important position in the lighting and backlight markets. The main specifications.
“In addition to higher light performance, LED market competitiveness is facing greater cost control pressures as product prices continue to decline. In recent years, more emphasis has been placed on product cost performance. Power package product development, and continue to erode the lighting application market for high-power packaging," said Zhang Luhua, marketing director of Smale.
In addition, the current large-power LED application market, in addition to covering the lighting market, display screen backlight, based on a wide range of product applications, including major applications such as automotive, flash, etc., this field was once high power development The center of gravity is currently shifting to medium power.
CSP involvement is of little significance
Indeed, since the beginning of this year, as the demand for the lighting market continues to grow, medium power packaging has become the mainstream of the market. Moreover, international manufacturers such as Europe, the United States, Japan, South Korea and Taiwan are also competing to enter the war.
“Since 2016, Lumileds has launched a powerful mid-power LED series in the first quarter. Taking the LUXEON 3535L HE Plus as an example, this product has received a lot of attention from the industry since its launch. It has shipped about 10 million units in March this year. Rahul Bammi, vice president of global marketing management at Lumileds, said that Lumileds' positioning is clear throughout 2016, and that it will gradually increase market share with a range of medium-power LED products.
At the same time, Bammi also mentioned that they still use the traditional lateral structure (Lateral) packaging technology on medium power devices. The new packaging technology will not become the mainstream of medium power LEDs in 2016. "Although vertical CRT LEDs and flip-chip LEDs have many advantages in high-power LED manufacturing, Lumileds believes that these technologies are costly and not suitable for medium power packages."
"In fact, CSP is currently widely used in the field of backlight applications, but there is still no cost performance in the lighting industry. Perhaps we should also thank the lighting factory for the constant compression of the cost, after the packaging factory is forced to Liangshan, Medium and small power LED products suddenly have a way out. With the price of small and medium power LEDs two years ago, CSP may have the advantage of substitution, but at such low prices, it has not seen much significance.†Jingke Electronics President Xiao Guowei said.
In fact, the current medium-power LEDs are gradually increasing the maximum input current to achieve higher light output, and meet the demand for high-bay and low-bay lamps that are currently on the market, as well as other devices that require smaller packages. Space LED lighting fixtures.
“This is a key factor in the final decision-making for customers who are concerned about cost control. For example, Lumileds horizontal structure LEDs are currently capable of achieving 194 lumens per watt of light output, which will ensure stable order requirements.†Bammi Said.
The High-tech Research Institute LED Research Institute (GGII) expects that the elimination of traditional lamps and the huge growth of the LED replacement lamp (TLED) market in the next three years will greatly help the growth of the low-power and medium-power LED industry. At the same time, unlike the development direction of the general LED lighting market, the mid-power LED market is expected to grow substantially in 2016.
